Agree because of the surfaces and bubbles that this is likely a cast copy.Note that there also is a G&G D228 described as "Tanka similar to gold type D221, but rather crudely engraved. Possibly a contemporary forgery"

It does look cast, no sharp detail to the legends, I've been caught out with about 4 modern forgeries in recent times although in every case I paid a really low price.

My latest one is an interesting looking Sikh copper coin from a seller I've bought off before, the second I unpacked it I could see it was a fake, in fact a lazy fake because the edge shows the join & also clear file marks where the sprue was cut off. I paid peanuts & it's not worth the cost of returning it.

My other ones have been buffed around the edge to remove evidence of a join which I presume most forgers would do.
